If you want to end up with the perfect mix, there are a few things that you have to consider when making your decision. The common parameters to compare between brands include the amount of calcium, magnesium, and the alkalinity.
The calcium compound is the most important component in the reef salt. Corals and other types of invertebrates need it for building their skeletons. The concentration recommended for good results is 400ppm. The PPM means part per million.
Magnesium is another important mineral to have in the reef water. It is often seen to be the most abundant trace mineral found in saltwater. Magnesium will work together with the calcium to help balance the alkalinity of the aquarium water. The recommended concentration is 1250 ppm.
The alkalinity is going to affect the pH level of the reef tank. With the addition of the salt, you can expect that the water will become more alkaline. You have to consider the alkalinity to make sure you understand the level of bicarbonates in the water. You might have to adjust the alkalinity where possible.
